Whenever any special assessment shall, in the opinion of the Council be invalid by reason of irregularity or informality in the proceedings, or if any court of competent jurisdiction shall adjudge such assessment to be illegal, the Council shall, whether the improvement has been made or not, or whether any part of the assessments have been paid or not, subject to the decision of the court, have power to cause a new assessment to be made for the same purpose for which the former assessment was made. All proceedings on such reassessment and for the collection thereof shall be conducted in the same manner as prescribed for the original assessment, and whenever any sum or part thereof levied upon any property in the assessment so set aside has been paid and not refunded, the payment so made shall be applied upon the reassessment or if the payments exceed the amount of the reassessment refunds shall be made.
